Definitions

  • the invention relates generally to devices and methods for generating ozone, and more particularly to a device and method for generating activated ozone structures.
  • the invention further relates to devices and methods for controlling pollutants and pests, including for cleaning, rendering harmless, neutralizing or treating toxic fluids and residues thereof, for example in emptied containers and lines, and the use of ozone and in particular activated ozone structures for the aforementioned purposes.
  • the invention is concerned, inter alia, with with a device for generating ozone, which has a high-voltage source and at least two electrodes arranged at a distance from one another, between which a dielectric is arranged which forms at least one flow path along the electrodes used for the dissociation of oxygen, at least one of the electrodes having holes.
  • Such devices are e.g. known from DE 41 41 025 AI and EP 0 571 592 B1.
  • a dielectric arranged between the electrodes serves to generate the so-called silent discharge.
  • ozone generation is based on the dissociation of molecular oxygen (O) initially to atomic oxygen (O), which leads to the formation of ozone (O 3 ) through subsequent attachment to oxygen molecules (O 2 ).
  • O molecular oxygen
  • O 3 atomic oxygen
  • O 2 oxygen molecules
  • the target was the ozone generation to use the ozone, although it was known that ozone is highly toxic and has a half-life of more than 5 hours. Many applications use the toxic area (killing germs, viruses, etc.), others use the oxidative area (bleaching processes, industrial oxidation, etc.). So the technical improvements mainly aimed at increasing the ozone yield.
  • the main problem here is that the energy consumption is relatively high, since most of the energy fed into the discharge is lost for the ozone synthesis and is ultimately converted into heat. Since the use of ozone has become uneconomical in many areas of application because of these losses, the long half-life for obtaining the O radicals necessary for oxidation processes and the subsequent destruction of the residual ozone, this medium is little used today relative to its possible uses.
  • Activated ozone structures can be produced:
  • a plasma which is characterized by a high electron temperature and a low gas temperature, is fundamentally necessary for the ozone synthesis in an electrical discharge.
  • An object of the invention is to provide an apparatus and a method which
  • This goal is achieved in a device for generating ozone, with a high-voltage source and at least two electrodes arranged at a distance from one another, with a dielectric arranged between them, which forms at least one flow path along the electrodes used for dissociation of oxygen, in that at least egg- ne of the electrodes has holes through which the flow path communicates with at least one discharge path.
  • a device for generating ozone having a high-voltage source and at least two electrodes arranged at a distance from one another with a dielectric arranged in between, which forms at least one flow path along the electrodes used for dissociation of oxygen, wherein at least one of the electrodes has holes .
  • This device for generating ozone is characterized in that the holes connect the flow path with a discharge path in which there are no high voltages.
  • gas from the flow path which is sometimes also referred to as a discharge gap, enters the at least one discharge path, namely both the gas introduced and also dissociated oxygen and already formed ozone.
  • the gas in the discharge path is in a protected room. This is because it is not exposed to any further shock discharges generated by externally applied voltages. Ozone that has already formed cannot therefore be destroyed by induced impacts. It follows that the proportion or the yield of ozone generated is achieved significantly higher than with the known ozonizers with the device according to the invention.
  • the fact that a very high proportion of activated ozone is formed is of considerable importance.
  • the decay time of activated ozone is in the range of seconds.
  • the decay time of neutral ozone, as it is generated with the known ozonizers is in the range of hours to days.
  • the invention therefore makes it possible to provide significantly more radicals at the same time, which is crucial for oxidation processes. So that is Ozone-equivalent oxidation ability with the same energy expenditure is about a factor of 10 3 greater than in the known devices and methods.
  • the device according to the invention and the corresponding method can be operated with significantly less or even completely without external cooling of the electrodes. This is because the gas emerging through the first holes in the discharge path, as seen in the direction of flow, is only slightly heated. It thus contributes to cooling the electrode in the discharge path both through direct contact with the electrode and by swirling the gas in the discharge path.
  • the passage through the gas-permeable electrode fulfills the plasma-physical conditions that are important for the optimal reaction phases, that the electron temperature must be higher than the temperature of the ions, atoms and molecules present in the gas.
  • both electrodes can also have holes for discharge paths, which increases the yield.
  • the outer boundary wall of the discharge paths can be arranged essentially parallel to the electrode (s) having the holes. As a result, the same conditions can be maintained in the flow path forming the discharge channel and in the discharge paths.
  • the outer boundary wall of the discharge paths viewed in the direction of the flow path, has a variable distance from the electrode having the holes.
  • the cross section can be larger or smaller in the longitudinal direction or larger and smaller like a wave. Due to the variable cross-section of the discharge paths, the pressure and surge flow conditions can be influenced in the desired manner.
  • the electrodes are preferably coated with electrically conductive material. In this way, more stable material can be used under pressure loads.
  • Each discharge path can be closed on the side facing the entrance of the flow path and open at its opposite end. This further training serves to design the flow guidance.
  • the flow path can be closed at its end opposite the input end.
  • all gas in the flow path is forcibly directed into and through the discharge path (s).
  • the electrode or the electrodes are divided in such a way that they each form a discharge path, the part facing the flow path having holes and the other part being closed. This training brings a better use of the wall effects.
  • both parts of the divided electrode can be electrically connected to one another. However, they can also be optionally connected electrically with different potentials. This enables the potential differences to be used to support the kinetics of the ionization.
  • the gas passage openings of the holes in the electrodes can be designed to be adjustable, preferably either uniformly or variably over the length of the flow path.
  • Each exhaust route can contain a gas permeable material.
  • the material contained reduces the available flow volume and thereby increases the molecular or body impact for O 3 formation.
  • the gas-permeable material is an electrically conductive material.
  • the gas-permeable material can be designed as a layer or layers and be coated with electrically conductive material.
  • the discharge path (s) is preferably connected to gas supply lines. This makes it possible to selectively supply desired gases, for example to support the formation of molecules or to reduce NO x formation.
  • the flow path can be connected to a pressure control unit, which enables the operation with either constant pressure, positive pressure or negative pressure.
  • a pressure control unit which enables the operation with either constant pressure, positive pressure or negative pressure.
  • the electrodes can be connected to a power supply unit, which can be operated either with direct current, alternating current or steep-edged pulse current.

  • a plurality of device or ozone generation units described above can be interconnected to form a unit group, which can increase the power throughput.
  • the units of a group can be communicatively connected to a common gas distribution unit.
  • Such an embodiment can also be used to increase the throughput performance and to adapt to room conditions.
  • the plasma-physical conditions also include the pressure in the discharge channel, which is called the flow path in the present documents.
